F-Body Europe

That head and cam package of course would be solid roller on the EXTREME side and wouldn't be no daily driver. Gonna need more than 10g's.

dude hate to burst your bubble but 600 RWHapees on a Daily driver without Nitrous is a pipe dream. I will break it down.
300 RWHapees average LS1
125 HC LS6 Stage II combination
10 underdrive pullies
30 exhaust with LT headers.
5 injectors
5 intake lid or simular setup
10 Diamond full floating pistons
? Lunati forged connecting rods.
? computer tune for above mods or it will not run anyway
10-30 Stroker crank
485-500 total and about $5000

You canot add Hapees with mods some mods take away because of the setup.
Nitrous is the only way to get over 600RWHP streetable hapees add $800
Super charger add $3000 good for 550 hapees
Turbo add $6000 good for 600 but not very streetable
My car is a crack baby and that is fine with me BTW I drive it all over Germany and race it. so you build your NA engine and let me know when you wanna play not trying to make you feel bad but NA and 600 RWHapees is a dream.
BTW a solid roller motor will not make 600 either NA but it can wind higher allowing the car to travel the 1/4 mile slightly quicker
